Frontman Jonathan Pierce revealed that the track was written with his best friend, the band’s guitarist Jacob Graham.

“‘Best Friend’ is a special song to us,” he told NME.COM. “It is my favourite song that we have. It’s the first song we wrote when starting the band and to write it with my closest friend, Jacob, makes it all the more sentimental for me.”

The frontman added that the duo decided to put a surreal twist on their friendship when writing the track.

“Rather than simply singing about our friendship, we decided to pretend Jacob died, and the song became much more beautiful to us,” he said. “Jacob feels like he died a long time ago anyways. His soul belongs to hell.”
